摘要： A process for manufacturing a cable includes the steps of conveying at least one conductor to an extruder apparatus; extruding an insulating coating layer radially external to the at least one conductor; longitudinally folding a metal tape around the extruded insulating coating layer, the metal tape bearing at least one adhesive coating layer in a radially external position; and extruding at least one continuous coating layer of at least one polyamide or a copolymer thereof around and in contact with the folded metal tape. The step of extruding the at least continuous coating layer is carried out at a draw down ratio not higher than 2.5, preferably, 1.2 to 2.0.
